The aim of the study was to evaluate and compare the effects of mesial movement of the maxillary and mandibular molars on the facial vertical dimensions following orthodontic treatment. Patients with an Angle Class I malocclusion were treated by four first premolar extractions and Begg fixed appliances (moderate and maximum anchorage groups), while those with an Angle Class II malocclusion were...

The treatment of class II malocclusion during adolescence is an important challenge for orthodontists, moreover, if there are other growth factors that hinder the reaching of a normal occlusion. Maxillary molar distalization is an orthodontic treatment method that has obtained an important diffusion since last years for correcting pure dental Class II malocclusion. In the past, several applianc...

INTRODUCTION The objective of this prospective study was to describe the clinical effects of a bone-supported molar distalizing appliance, the dual-force distalizer. METHODS The study group included 16 patients (mean age, 14.3 years) with Class II molar relationships. Study models and lateral cephalograms were taken before and after the distalizing movement to record significant dental and sk...

OBJECTIVE To evaluate the efficiency of the Frog appliance (FA) alone or in combination with headgear for distalizing the maxillary molars. METHODS Fifty patients (25 males and 25 females) aged 12.6 - 16.7 years who received treatment for Class II malocclusion at the Orthodontic Clinic of Al-Baath University were selected for this study and randomly divided into 2 equal groups. Maxillary mola...

This study aimed to examine the skeletal, dental, and soft tissue effects of the implant-supported pendulum (ISP) and the zygoma anchorage system (ZAS) used for the distalization of maxillary posterior teeth. Among 30 patients showing Angle class II malocclusion, 15 patients with a mean age of 14.3±1.6 years and treated with ISP were included in the first group; 15 patients with a mean age of 1...

OBJECTIVE The aim of this study was to evaluate the reliability of measurements obtained after the superimposition of three-dimensional (3D) digital models by comparing them with those obtained from lateral cephalometric radiographs and photocopies of plaster models for the evaluation of upper molar distalization. METHODS Data were collected from plaster models and lateral cephalometric radio...

The purpose of this study was to evaluate treatment effects of Jones jig appliance during class-II molar correction with a focus on the magnitude of maxillary first molar distalization, its tipping, extrusion and rotation as well as anchorage loss at premolarincisor unit. A complete set of pre and post distalization records including history, clinical examination, Lateral cephalometric radiogra...

In the recent years, nonextraction treatment approaches and noncompliance therapies have become more popular in the correction of space discrepancies. One of the conventional approaches for space gaining in the arches without patient compliance is done by using certain extra oral appliances or intraoral appliance. The greatest advantage of certain appliances like fixed functional and molar dist...

Palatal implant for distalization of molars can be used by two methods: I] It can be directly connected to the teeth that have to be moved by means of a distalizing device {direct method}, so that the reactionary forces are completely dissipated on the implant. II] It can be used as a reinforcement anchorage unit, by means of transpalatal bar connecting the first premolars and the implant; in t...

JCO/MAY 2003 C II nonextraction treatment involving headgear and Class II elastics often requires exceptional patient cooperation. As a result, more and more clinicians are prescribing “noncompliance” molar distalization appliances. These appliances have some negative side effects, however, including a significant loss of anchorage that can manifest itself in mesially tipped bicuspids, anterior...
